I have to hit the gym to keep me sane, I'd advise any IM who spends most of his day on a computer. It's very bad for you mentally and physically, it's not natural. I would get so bad that'd I'd wither away on caffeine and not even a meal a day. Wasn't getting sun, vitamins, protein, the normal things that humans naturally absorb.
If working out isn't your thing, just do anything physical for 30 minutes to an hour whether it's skateboarding, skating, playing hockey, football, etc..
Here's what I take every morning:
2000 mg Vitamin C
2000 mg vitamin D drops(water soluble, I mix this in with the vitamin c drink.)
Multivitamin if you want, I don't take these though. Fishoil also helps you look good.
5000 mg B12 drop under the tongue.
Whey Protein Shake with a big bowl of cereal.
Then I have my coffee and I hit the gym. Normally if you're trying to put on some weight you want to wait until the hour after you're done working out to slam it. Remember to keep yourself hydrated with water > Caffeine and stay away from the red bulls.
You don't have to kill yourself in the gym either, do what you can, just get your heart and blood pumping. I start with cardio, I jog about a mile and then I hit the weights. A half mile is fine, just get the blood pumping as I said.
Try these above steps for a couple of weeks - a month and report back on how you feel! Breaks and exercise are a must if you want to keep your sanity and flourish in this industry, it helps keep focused and get your creative energy flowing like crazy.

And don't forget to eat clean too.
